Fertility, Sperm Health, and Nutrition Before and During Pregnancy | Dr Federica Amati

Dr. Federica Amati
Show Notes

This episode challenges the assumption that a child's health journey begins at birth. Dr Federica Amati, Head Nutritionist at ZOE, explains how the months before conception and the first 1,000 days shape fertility and lifelong health. She discusses the 90-day preconception window for both parents, the surprising role of a father's metabolic health in brain development, and what the dramatic decline in sperm counts means for individuals. The conversation balances striking science with a compassionate, guilt-free approach, emphasising the policy and environmental factors that often outweigh individual choices.
